SMOKE-CONSUMER,

' Application filed. September To all whom it may concern:

Be it known that l, HENRY S. AYLING, a citizen of the United States, and a resident S of Danville, in the county of Vermilion and State of Illinois, have invented a new and Improved Smoke-Consumer, of-which the following is a full, clear.,- andexact description. I i I One object of the invention is'toprovide a new and improved smoke, consumerfor the use of locomotive furnaces and other furnaces using coal, oil, wood or other fuel, and arranged to insure completecombustion fuel and to greatly economize j in the amount of the fuel employed.

Another object is to increase the efficiency of the engine by a quick generation of steam,

increase in the steam pressure and enlargement of the exhaust nozzle of a locomotive.

In order to produce the-desired result,.use is'made of pipes having portions perforated on the under side and extendin within the.

' fire box of the boiler immediate above the burning fuel on the grate of the fiife'box,

opening "into f the the terminals of the pipes H to pass into" the;

atmosphere to allow air pipes to be heated therein and 'to-issue through the perforated; portions to mixwith the gases arising from the ,burning fueljin the fire box. Usefis also made 'of diaphragms in the pipes above'the to cause thefair to travel over the diaphragms to be thoroughly heated before j i reaching the perforated portions.

A practical embodiment of the invention is represented in ings forming a part ofthis specification, in which similar charactersof reference indicate corresponding parts in all the views. Figure 1 is a longitudinal central section of the fire box portion of a locomotive boiler provided with the smoke consumer; Fig.2 is a cross section of the same on the ine 23 looking in the forward direction of the arrow y; Fig. 3 is a similar view of the same on the line 23 looking rearward in the direction of the arrow m; Fig. 4 is an enlarged longitudinal central section of one of the air delivering pipes and showing more particularly the construction of the diaphragms; and Fig. 5 is a cross section of the same on the line 5-5 of Fig. 4.

Within the fire box 10 of a steam boiler furnace 11 of any approved construction,

are arranged side air delivering pipes 12 Specification of Letters Patent the gases arising in the-burning fuel. Use is perforations as plain} the accompanying drawa, 1915. Serial No.- 19,761..-

through the bottom ofthe' fire box to open into the atmosphere and thus allow the fresh air to pass through the pipes 14: and 15 into the pipes 12/ The lower portions of the pipes112 are provided with perforations 16 and within. each pipe 12 are arranged diaphragms' 17 and 18 having their outer ends .terminatingin turned down flanges 19 (see F g. 4') while their inner ends are spaced apart, It will be noticed that the d1aphragms-17 and 18 extend above the perforations pipes 14i 15-p'asses over the diaphragms 17 and 18 to the middle of the pipe 12 which then passes down under the diaphragms to the perforations 16 and out of the same into formed to, consume the smoke and to utilize japproximately all the ,heat units contained v also made .of top air delivering p pes 20 extending through the back-of the the box near the top thereof in ia' downward and forward direction to pass thro hathe front wall of the fire box, indicated in Fig. 1. The pipe 20 has the; lower forward portion provided with perforations 21 and diaphragms similar to the diaphragms 17 and 18 are preferably arranged in the pipes 20. It will be notidldthat the pipes 20-deliver fresh air to the. gases that pass upwardly and for- 16 and the air entering the 2 I from theburning of the i fuel so that a highly inflammable mixture is wardly infhe middle portion of the fire box soijthat such gases receive a full supply of -freshlair;to insure complete combustion.

Asa further aid to complete combustion airiisdelivered to the gases front" ofv the fire boxfand for this purpose usevis made of back air delivering pipes 22 and front air delivering pipes 23. The pipes 22 extend *transversely at the back of the fire box 10 and their outer ends are closed by plugs 24: and the inner ends are connected with pipes 25 leadingto the atmosphere to supply the said pipes 22 with fresh air, the lower portions of the pipes 22 being provided with perforations 26 similar to. the perforations 16 and 21. The front air delivering pipes 23 extend transversely at the back and at the forward side portion of the fire box being provided with perforations 30 for conducting the .air into the gasesarising "from the burning fuel at the front of the fire box.

It will be noticed that by the system of pipes employed, a large amount of fresh air is passed into thefire box to mingle with the gases arising from the burning fuel to insure complete combustion.

It is understood that the draft in the fire box causes the. fresh heated air to be drawn through the perforations of the several air delivering pipes. It is also understood that the perforations in each pipe have an aggregate area equal or somewhat in excess of the aggregate area of the endsof the air admission p1pe..

claim as new and desire Having thus described my invention, I to secure by Letters Patent:

1. A smoke consumer for, furnaces, comt eburning fuel inthe fire box of the fur.- thejair delivering pipes being provided eir lower portions with perforations,

the saidair delivering pipes being connected "tions,

at the ends withthe atmosphere-to admit air 'to the said air delivering pipes, and two diaphragms extending lengthwise within each air supply pipe abovethe perforathe" diaphragms terminating short other near the middle of the pipe diaphragms being of eac and the turned the ends of'the pipe to travel over the diaphragm's into the perforated portions of the 2. A smoke consumer for furnaces,- comprising side air delivering pipes-extending re box at the sides thereof, the" said side air delivering pipes being connected at their'ends with the atmosphere and having their lower portions perforated, and a plurality of top air delivering pipes extending longitudinally within the fire box from the back of the fire boxin a downward and forward direction to the front of the same, the said top delivering the ends of each of pipes opening into ward bottom portions in the fire extending above portion perforated, and pipe out through the perforations into the box. a

the atmosphere and the forward bottom portions of the said top delivering pipes being perforate.

3. A smoke consumer for furnaces, comprising side air delivering pipes extending longitudinally within the fire box at the sides thereof, the said air delivering pipes being connected at their ends with the atperforated, top air delivering pipes extending longitudinally within the fire box in a downward and forward direction, the ends of each of the said top delivering pi es opening into the atmosphere and the orof the said top delivering pipe being perforated, each side and top delivering-pipe being provided with two diaphragms having their outer ends engaging the pipe and,their inner endsspaced apart near the middle of the pipe, and back air delivering pipes extending transversely box at the back thereof and above the burnin fuel in the fire box, the said divering pipes having their bottom portions-perforated.

ke consumer for furnaces, coinprising side air delivering pipes extending longitudinally within the fire box at the sides thereof, the said side air delivering pipes being each connected at its ends with the atmosphere and having its lower portions pipes extendding transversely in the fire box thereof and above the burning fuel in the fire box, the said back air delivering pipes being each connected at one end with the atmosphere and having its bottom front air delivering the said front air delivering pipes opening name to this specification in the presence of two subscribing witnesses.
